目前,希有元素的化学冶金(卽由矿石或其他天然资源到純化合物的过程)的研究,可能存在着下列两个发展方向:其一是寻找新的或者改善已有的处理单一希有元素矿物原料的工艺过程,以及阐明其中的物理化学反应机理。其二是寻找新的綜合处理复合多金属的希有元素矿物原料的工艺过程,例如处理复合希土的铌钽钛酸盐类型的矿物;自盐湖滷水中提取希有碱金属;綜合利用含有多种希有分散元素及貴金属的有色冶金工业的废料或中間产物等等。不論是对单一矿物原料的加工处理也好,更不論是对复合原料的处理和綜合利用也好,氯化法是一个很有价值的和有发展前途的方法。氯化反应按其本貭来說,是一种火法冶金过程,卽在高溫下用氯气作用于
At present, there may be two directions for the development of elemental chemical metallurgy (卽 from ore or other natural resources to pure compounds): one is to find new or improve the existing treatment of single elemental mineral raw materials The process, as well as elucidation of the physico-chemical reaction mechanism. The second is the search for a new process for synthesizing a composite multimetallic elemental mineral material such as a niobium-tantalum titanate type mineral that treats composite rare earths; extraction of an alkali metal from salt lake brine; Scattered elements and precious metals, non-ferrous metallurgy industry waste or intermediate products and so on. Whether it is a single mineral raw material processing Ye Hao, not to mention the composite material handling and comprehensive utilization Ye Hao, chlorination is a valuable and promising method. The chlorination reaction, in its essence, is a pyrometallurgical process in which chlorine gas acts on
